What is the time limit to file a review against the decision of the Registrar?

Section 127(c) of the Trade Marks Act, 1999 gives the Registrar power to review his own decision on an application made in the prescribed manner. Rule 119 of the Trade Marks Rules, 2017 requires that application, on Form TM-M, "within one month from the date of such decision", and the Registrar may on request allow "a further period not exceeding one month thereafter".

Three months is the period for an appeal to the High Court under section 91, not for review.
